In Oregon, a string of crashes involving over 25 vehicles, mostly semi-trucks, occurred across a quarter-mile stretch of Interstate 84, east of Baker City.
Kaleb Whitby was wedged between two semi-trucks in his Chevy pick-up truck, according to The Oregonian.
A likely combination of low visibility and freezing temperatures contributed to hazardous travel conditions around Saturday at the time of the accident, according to AccuWeather.com meteorologist Mark Paquette.

"Thank God that I'm still alive," Whitby told The Oregonian. "Now I've got to figure out why."
Whitby walked away with only a few scratches. Among the 100 people involved in the pileup, none were killed and 12 were injured, according to The Oregonian.
Black ice may be the main cause of the accident, according to The Associated Press.
"Black ice is the type of ice that is put down by freezing fog," Paquette said.
Because driver cannot see it, black ice is more dangerous than other forms of ice, Paquette added.
Weather Saturday around the time of the accident was in the upper 20s. An inversion of warm air resting on cold air created unstable conditions including freezing fog, which can deposit a thin layer of ice over roads. Not only can the fog coat the roads in ice, but the sun is unable to penetrate through to warm the roads.
Paquette said, below-freezing temperatures and low visibility are "a recipe for disaster for travelers."
